The NEC allows 26.
No, the bare copper grounding conductor can not be in a conduit with other conductors. It can be in conduit by itself to provide mechanical protection for the wire.
It depends on the wiring, the current load in the wiring , and the distance. The NEC Code book has the charts for this.And the size of the conduit.
Metal conduit must be buried to at least 6 inches. Non-Metal conduit must be buried to at least 18 inches. Direct bury wire must be buried to at least 24 inches. This is what the NEC requires but your local codes may be even deeper. Check with your local utility to see what they require.

Welding is not allowed by the NEC (United States' code).
The National Electrical Code (NEC) requires that conduit fill in electrical installations should not exceed 40 of the cross-sectional area of the conduit to ensure safe and efficient wiring.
The NEC PVC conduit fill table provides information on the maximum number of conductors that can be safely installed in a PVC conduit based on the size of the conduit and the size of the conductors.
The maximum fill capacity allowed for NEC conduit fill in electrical installations is 40.
When determining NEC conduit sizing for electrical installations, factors to consider include the number and size of conductors, the type of insulation, the ambient temperature, the conduit fill ratio, and the voltage drop.
The NEC pipe fill chart provides information on the maximum number of cables that can be safely installed in a conduit based on the size of the conduit and the diameter of the cables.
The appropriate NEC conduit size for the electrical wiring in this project should be determined based on the number and size of the conductors being used, as well as the specific requirements of the project. It is recommended to consult the NEC guidelines and work with a qualified electrician to determine the correct conduit size for the wiring.
The NEC conduit fill table for PVC conduits provides guidelines on the maximum number of conductors that can be safely installed in a PVC conduit based on its size. It helps ensure proper spacing and prevents overheating of the conductors.
The conduit fill chart in the NEC provides information on the maximum number and size of electrical wires that can be safely installed in a conduit. This helps determine the appropriate size of conduit to use for specific electrical installations, ensuring compliance with safety standards.
The NEC conduit fill chart provides information on the maximum number and size of electrical wires that can be safely installed in a conduit based on the conduit size and type of wires being used. This helps determine the appropriate size of conduit needed for specific electrical wiring installations to ensure safety and compliance with regulations.
